Help needed with CPU perfromance, X79 Monterey

Hello guys,

I'm a bit of a beginner to hackintoshing but I managed to get Monterey installed onto an ASUS P9X79 PRO. However, whilst benchmarking CB R20, I noticed that CPU performance was quite terrible. I'm talking less than half of what it should be. I suspect it could be a power management issue since my temperatures are steady at 30 or so degrees celsius.

Does anyone have experience with this? What can I do to fix this?
